A Hull-based UKIP official has received death threats after his mobile phone number was printed in Private Eye.

The satirical magazine featured a spelling mistake on Mike Hookem's business card.Mr Hookem, who is standing in this year's Euro elections and is the party's Yorkshire regional chairman, said: "As a result I've had two anonymous death threats made against me.

"I have told the police and Special Branch officers have been out to see me and are treating this matter seriously.

"I am disgusted and angry that Private Eye was irresponsible enough to print all the details and not block out my phone number.

"I enjoy reading the magazine and its irreverent style but as a long-standing professional publication they should have shown more consideration.

"I have written to them demanding an explanation but, of course, the harm has been done. Luckily I am not the sort of person to be easily intimidated, but such threats are upsetting."
